Construction mastic for commercial buildings in Wallingford
Refurbishment work needs a slightly different approach from new build. Old beads come out completely, as fresh silicone can’t grip old and the asbestos survey is checked first on older stock. After that, the joints are prepared and sealed to the specification. If you’re dealing with old sealant on a refurbishment that needs stripping before new work and mastic snags holding up handover, we can help, whatever the surface. One point of contact handles commercial sealant work in Wallingford from the first photos to the final walk-round, for single jobs and planned programmes alike.
Around places like Wallingford, a lot of construction is the conversion of older buildings, which leaves joints between old walls and new frames that need a sealant able to take the movement, in a colour the planners or architect are happy with.
Our workmanship is guaranteed for 12 months, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Leave it or put it right?
Leaving mastic to whichever trade is fitting the element can look cheaper on paper. In practice it often means different standards, gaps in responsibility and snags nobody owns. One mastic subcontractor for the lot keeps it simple, with the same standard on every plot. A failed joint lets water into a building whatever its size. Catching it early means a reseal rather than repairs.
What a job costs comes down to how many linear metres there are, what has to come out first and how the joints are reached. Call for a quote when you’re ready.

Cost factors for mastic packages
Each job is priced on its own details. The things that drive the figure:
- Phasing around occupants
- Joint width, depth and condition
- Travel to remote or island sites
- The site’s rules and procedures
We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we’ll price your job on its own details.
What we need to price the job
However big the job, these details speed things up:
- The site address and postcode
- Drawings or a marked-up plan, if available
- Access details, including height
- When you need the work done
The quickest route to a quote is a few photographs and the site postcode. Send them through the quote form, or speak to us on 01277 525 020 or send photos by email if you’d rather talk the job through.
Our process
Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. If neighbouring businesses or buildings around Wallingford need work too, visits can be combined. Tell us your site hours and we will plan around them.
- We walk the site or review drawings to understand the package.
- A fixed quote sets out scope, products and phasing.
- Site paperwork is confirmed and our CSCS-carded applicators are inducted.
- Sealing follows the programme as areas are released.
- Problems we find, such as oversized gaps, are raised right away.
- The package is closed out, snags cleared and backed by our 12-month guarantee.
What we need from you
- Point out parking and an unloading spot
- Share your working hours and any access restrictions
- Send any specification or drawings in advance
Request a quote
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. For smaller jobs, photos and a description will do.

Different surfaces, different methods
Internal decorators’ caulk
Where the specification calls for it, acrylic decorators’ caulk goes on non-moving internal gaps before painting. It’s paintable and suits gaps that don’t move.
Snagging before handover
Snags usually come from damage by following trades, missed joints or poor earlier work. Snagging can be included or priced separately.

When something else is needed
Honesty saves time and money. Fresh joints won’t solve:
- Specifying the product where the designer hasn’t
- Oversized gaps that need packing or adjustment by others
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
Not sure which it is? You can call the office on 01277 525 020 or email a schedule or drawings and we will tell you honestly before you book.

Building and refurbishing in Wallingford
The South East is one of the drier parts of the UK. Winter mornings still bring frost and condensation on frames and panels, so we time external mastic for dry faces and agree it with the site team. The area within 2 miles of Wallingford holds a number of hotels. When hotels extend or refit, the work is usually squeezed between peak periods, mastic included.
When a school such as Fir Tree Junior School is extended or refurbished, the mastic package is often squeezed into the holidays. Hospital estates such as Wallingford Community Hospital (to the south of Wallingford) tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan. Historic houses such as Brightwell Manor, 1.7 miles to the north-west of Wallingford, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.
